Find the area of the figure below composed of a square and four Semicircles rounded to the nearest tenths place 

We can start by creating a table to organize the information:

                  Likes Chocolate (c) Does Not Like Chocolate (~c) Total

Likes Sprinkles (s) 0.25                                                           0.40

Does Not Like Sprinkles (~s)            0.60

Total 0.70                                               0.30                       1.00        

We are given that 40% of friends like sprinkles, so we can fill in that cell of the table. We are also given that 25% of friends who like chocolate also like sprinkles, so we can fill in the cell for likes chocolate and likes sprinkles as 0.25.

To find the proportion of friends who like sprinkles and chocolate, we need to divide the number of friends who like both by the total number of friends who like sprinkles:

proportion = likes chocolate and sprinkles / likes sprinkles

proportion = 0.25 / 0.40

proportion = 0.625

So, approximately 62.5% of friends who like sprinkles also like chocolate.

Answer:

(- 1.5, - 4.5 )

Step-by-step explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

here (x₁, y₁ ) = (- 2, - 4 ) and (x₂, y₂ ) = (- 1, - 5 ) , then

midpoint = ( [tex]\frac{-2-1}{2}[/tex] , [tex]\frac{-4-5}{2}[/tex] ) = ( [tex]\frac{-3}{2}[/tex] , [tex]\frac{-9}{2}[/tex] ) = (- 1.5, - 4.5 )

The probability of drawing a second green ball, given that the first ball is green is equals to the 11/24.

We have specify the probabilities values for selecting balls without replacement,

Probability of choosing two green ball

= 11/50

Probability of choosing one green ball

= 12/25

We have to determine the probability of drawing a second green ball, given that the first ball is green. Let us consider the two events as

A = Probability of second ball green

B = probability first ball is green = 12/25

P (A and B) = P (Both balls are green)

= 11/50

Fir determining the required probability we use conditional probability formula,

P ( A/B ) = P( A and B) / P (B)

Plug all known values in above formula,

P ( A/ B) = ( 11/50)/(12/25)

= (11 × 25)/(50×12)

= 11/24

Hence, required probability value is equals to 11/24.

Answer: To find the length of the horizontal sides of the rhombus, we need to find the distance between points (1, 3) and (9, 7), which is the same as the distance between points (4, 7) and (6, 3).

Using the distance formula:

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

d = √[(9 - 1)² + (7 - 3)²]

d = √[64 + 16]

d = √80

d ≈ 8.94

So the length of the horizontal sides of the rhombus is approximately 8.94 units.

To find the perimeter of the rhombus, we need to find the distance between all four vertices and add them up.

Using the distance formula:

d₁ = √[(4 - 1)² + (7 - 3)²] = √25 = 5

d₂ = √[(9 - 4)² + (7 - 7)²] = √25 = 5

d₃ = √[(6 - 9)² + (3 - 7)²] = √16 + 16 = √32 ≈ 5.66

d₄ = √[(1 - 6)² + (3 - 7)²] = √25 + 16 = √41 ≈ 6.40

Perimeter = d₁ + d₂ + d₃ + d₄ = 5 + 5 + 5.66 + 6.40 ≈ 22.06

So the perimeter of the rhombus is approximately 22.06 units.

Step-by-step explanation:

Factor f(x)=3x³ + 7x²2-18x+8 into linear factors is f(x) = (x+4)(3x+7)(x-7/3)

In mathematics, factorization (also known as factoring) is the process of finding the factors of a given mathematical expression or number. A factor is a number or expression that divides another number or expression exactly, leaving no remainder.

For example, the factors of 6 are 1, 2, 3, and 6 because these are the numbers that divide 6 exactly with no remainder. Similarly, the factors of x² - 4 are (x+2)(x-2) because when we multiply these two expressions together, we get x² - 4.

If -4 is a zero of f(x), then x+4 is a factor of f(x) by the factor theorem

f(x) = (x+4)(3x² - 5x - 78)

To factor the quadratic further, we can use the quadratic formula or factoring by grouping:

3x² - 5x - 78 = 0

x = (5 ± √(5² + 4(3)(78))) / (2(3))

x = (5 ± 19) / 6

x = -7/3 or x = 13/3

Therefore, we have:

f(x) = (x+4)(3x+7)(x-7/3)

The graph of the equation y = x² + 5 is symmetric with respect to the y-axis, the correct option is (b).

To determine the symmetry of the graph, we can substitute (-x) for x in the equation and simplify:

y = (-x)² + 5

y = x² + 5

Since the equation is unchanged when x is replaced by (-x), the graph is symmetric with respect to the y-axis.

We can also see that the graph is not symmetric with respect to the x-axis or the origin. To check for symmetry with respect to the x-axis, we can substitute (-y) for y in the equation:

(-y) = x² + 5

y = -(x² + 5)

The equation is not the same as the original equation, so the graph is not symmetric with respect to the x-axis. Similarly, to check for symmetry with respect to the origin, we can substitute (-x) and (-y) for x and y in the equation:

(-y) = (-x)² + 5

y = x² + 5

The equation is not the same as the original equation, so the graph is not symmetric with respect to the origin.

In any given circle, the measure of an inscribed angle is one-half the measure of the central angle that intercepts the same arc.

Answer:

Let’s start by defining the variables:

Let x be the number of rings manufactured per day.

Let y be the number of chains manufactured per day.

The total number of rings and chains manufactured per day is at most 24. Therefore, we have:

x + y ≤ 24

It takes 1 hour to make a ring and 30 minutes to make a chain. Therefore, we have:

1x + 0.5y ≤ 16

The profit on each ring is Rs. 300 and that on each chain is Rs. 190. Therefore, the total profit can be calculated as:

Total Profit = 300x + 190y

We want to maximize the total profit. This can be done by solving the above equations using linear programming.

The solution to this problem is x = 12 and y = 12. Therefore, the firm should manufacture 12 rings and 12 chains per day to earn the maximum profit
